[0037] See also Figures 1 to 5 An embodiment of the present application provides a fluid path module 100 for a thermal management system 200 of a vehicle, comprising a main body plate 10. A plurality of flow paths are constructed in the main body plate 10, and all the flow paths include at least one first flow path 11 and at least two second flow paths 13, and all the second flow paths 13 are connected in parallel and communicate with the first flow path 11.

[0038] The flow path of the liquid path module 100 is used to circulate the liquid used for transferring heat in the thermal management system 200. The liquid can be but is not limited to water, refrigerant, etc. The following embodiments are described using cooling water as an example.

[0039] The first flow path 11 can be used to connect to the radiator 202 and / or the heat exchanger 201, and each second flow path 13 is respectively used to connect to a cooling target 203. It can be understood that the flow path is constructed in the main plate 10, and its extension direction is perpendicular to the thickness direction of the main plate 10. The port of the flow path is formed on the surface of the main plate 10 and serves as a water inlet or outlet.

[0040] In one embodiment, cooling water flows from the radiator 202 and the heat exchanger 201 to the first flow path 11 of a liquid path module 100, and then flows from the first flow path 11 to each second flow path 13, and then flows to the cooling target 203 that needs to be cooled for heat exchange. The cooling target 203 includes but is not limited to a motor controller, a DC / DC converter, a motor, etc. The cooling water after heat exchange with the cooling target 203 can pass through another liquid path module 100, and each of its second flow paths 13 converges into the first flow path 11, and finally flows back from the first flow path 11 to the radiator 202 and / or the heat exchanger 201.

[0041] The main body plate can be manufactured and processed from metal or non-metal, and the direction, diameter, and number of the flow paths inside the main body plate can be determined according to the architecture of the thermal management system 200 .

[0042] In the above-mentioned liquid circuit module 100, the flow path is formed in the same main body plate 10, and cooling water can be transported to different cooling targets 203 through each second flow path 13, thereby realizing the integration of the flow path. In this way, the flow path included in the liquid circuit module 100 with integrated flow paths is more regular and the direction is more standardized. Compared with the pipelines arranged in a staggered manner in a three-dimensional space, the overall space occupied by the liquid circuit module 100 is smaller and the layout is more regular.

[0043] In some embodiments, the fluid path module 100 further includes a plurality of pipe joints 30 , all of which are disposed on the main body plate 10 and are respectively connected to each flow path, and all of the flow paths are connected to external pipelines through the pipe joints 30 .

[0044] The pipe joint 30 is connected to the port of the flow path and is used to connect and communicate with the external pipeline. In other words, the two ends of the pipe joint 30 can be connected and communicated with the port of the flow path and the external pipeline respectively.

[0045] In this way, the liquid circuit module 100 can be connected with the external pipeline through the pipe joint 30, so as to transport the cooling water flowing therein to the outside.

[0046] Furthermore, all ports of the flow paths are formed on the circumferential side of the body plate 10 in the thickness direction thereof. The pipe joint 30 is provided on the circumferential side of the body plate 10 in the thickness direction thereof and communicates with the ports of the flow paths.

[0047] It can be understood that the pipe joint 30 is generally cylindrical, and its axial direction intersects with the thickness direction of the main plate 10 . Preferably, the axial direction of the pipe joint 30 is perpendicular to the thickness direction of the main plate 10 .

[0048] In this way, compared with the case where the ports of the flow path are formed on the opposite sides of the main plate 10 in the thickness direction, the main plate 10 forms the ports of the flow path on the circumferential side around itself in the thickness direction, and the pipe joint 30 is correspondingly arranged on the circumferential side, which helps to reduce its space occupancy in the thickness direction and utilize the space more rationally.

[0049] Furthermore, the pipe joint 30 can be detachably connected to the main body plate 10, and can be specifically connected to the main body plate 10 by screw connection or quick plugging. In this way, the pipe joint 30 is quickly connected to the main body plate 10, and can be disassembled as needed.

[0050] It can be understood that the inner diameter of the flow path can be set as required, and the inner diameter of the pipe joint 30 can be designed according to the aperture of the flow path.

[0051] In some other embodiments, the flow path of the main plate 10 may not pass through the pipe joint 30, but may be directly connected to the external pipe by quick plug, which is not specifically limited here.

[0052] In some embodiments, the fluid path module 100 further includes at least one blocking member (not shown), which can detachably block the fluid path. The blocking member can be, but is not limited to, a blind plug.

[0053] It can be understood that the blocking member can block the flow path through the blocking pipe joint 30. After the flow path is blocked and the cooling water cannot flow normally, it means that the flow path is invalid, and the remaining unblocked flow paths of the liquid path module 100 continue to work as effective flow paths.

[0054] In this way, the same liquid path module 100 can change the number of water inlets and outlets by adding or reducing plugging parts, thereby changing the entire effective flow path shape of the liquid path module 100, so that it can be used in different environments and adapt to different thermal management solutions.

[0055] In some embodiments, the main body plate 10 is further configured with at least one sensor interface 15 , and the sensor interface 15 is connected to the flow path.

[0056] It is understandable that the sensor interface 15 can be used to install temperature, pressure and other sensors to help detect the temperature, pressure and other parameters of the cooling water in the flow path. The location where the sensor interface 15 is installed can be selected as needed, and the number can also be multiple.

[0057] The sensor interface 15 can facilitate installation of sensors on the fluid circuit module 100 to help understand the working conditions of the thermal management system 200 .

[0058] In some embodiments, a fixing interface 17 is also constructed on the main body panel 10, and the fixing structure is used to cooperate with the connecting piece to fix the main body panel 10 to the vehicle chassis, frame and other external components.

[0059] In a specific machine, the main body 10 is generally rectangular, and the number of the fixing interfaces 17 is four, and the four fixing interfaces 17 are respectively located at the four corners of the main body 10. In some other embodiments, the number and position of the fixing interfaces 17 can be determined according to the required fixed positions, and are not specifically limited here.

[0060] In one embodiment, the first flow path 11 is along a first direction (eg Figure 3 The second flow path 13 extends in the second direction (as shown in the X direction). Figure 3 The first direction and the second direction intersect each other. An intermediate flow path 19 is also configured in the main body plate 10. The second flow paths 13 are connected in parallel through the intermediate flow path 19 and are connected to the first flow path 11.

[0061] The second flow path 13 flows between the two ends of the first flow path 11 through the intermediate flow path 19. The two ends of the first flow path 11 form ports on both sides of the main body plate 10 in the first direction, and one end of the second flow path 13 forms a port on one side of the main body plate 10 in the first direction. The sensor interface 15 is formed between the two ends of the first flow path 11 and is specifically located at a position on the first flow path 11 that communicates with the intermediate flow path 19.

[0062] Please also read Figures 6 to 9 In another embodiment, the fluid path module 100 further includes a multi-way valve 50 , and at least a portion of the second flow path 13 is connected to the first flow path 11 through the multi-way valve 50 .

[0063] The multi-way valve 50 may be, but is not limited to, a three-way valve, a four-way valve, etc., which is not specifically limited herein.

[0064] The first flow path 11 and the second flow path 13 connected through the multi-way valve 50 can be flexibly connected through the multi-way valve 50 to meet the cooling water flow control needs.

[0065] Furthermore, the main body plate 10 is also configured with a valve body interface 111 , and is connected and communicated with the multi-way valve 50 through the valve body interface 111 .

[0066] See also Fig.10 The present application also provides a thermal management system 200 , including the above-mentioned liquid circuit module 100 .

[0067] In some embodiments, the thermal management system 200 further includes a heat exchanger 201 and / or a heat sink 202 .

[0068] The thermal management system 200 includes at least two liquid circuit modules 100. In the flow direction of the liquid, one liquid circuit module 100 is arranged upstream of the heat exchanger 201 and / or the radiator 202 and downstream of the cooling target 203, and the other liquid circuit module 100 is arranged downstream of the heat exchanger 201 and / or the radiator 202 and upstream of the cooling target 203.

[0069] Specifically, the thermal management system 200 further includes a water pump 204 , and the water pump 204 is disposed between the heat exchanger 201 and / or the radiator 202 and the liquid circuit module 100 .

[0070] In this way, the cooling water in the thermal management system 200 can flow from the heat exchanger 201 and the radiator 202 to one liquid circuit module 100 driven by the water pump 204, and flow to different cooling targets 203 through the liquid circuit module 100, and then converge through another liquid circuit module 100, so that all the cooling water flows back to the heat exchanger 201 or the radiator 202. Among them, at least two liquid circuit modules 100 can replace all the original three-way valves, which helps to simplify the thermal management system 200.

[0071] The present application also provides a vehicle, comprising the above-mentioned fluid circuit module 100 or the above-mentioned thermal management system 200.

[0072] In some embodiments, the vehicle further includes a thermal management valve body, and the fluid circuit module 100 is disposed below the thermal management valve body and serves as an underbody guard plate of the vehicle.

[0073] In this way, the liquid circuit module 100 can not only be used as a part of the thermal management system 200 for conveying cooling water, but can also be used as an underbody guard plate, which helps to save space in the vehicle.

[0074] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
